**Construction of the tower**

The tower is built of pure structural wrought iron. It makes the structure relatively extremely light. The construction of the tower marked a great architectural achievement. Total 18038 pieces of iron were fitted together by 2.5 million rivets. Around 300 workers completed the construction of the tower in just 2 years, 2 months, and 5 days. The construction was started on July 28, 1887. The four foundations were started at the same time. According to Gustave Eiffel’s calculations, it showed that the pressure on each floor of his tower would not exceed that of a building and told the residents not to fear possible hazards. The foundations were built over heavy blocks of concrete which were designed to carry the load of 4 masonry bases which themselves receive the load of the heavy metal structure. The foundations contain various rooms on the pedestals like the warden’s room, technical rooms of the elevators, etc. The pillars were constructed over the pedestals. At the starting point of pillars, there was a problem of inclination. The pillars should meet the first level at the same altitude. There was a fear of having an unacceptable gap at the finishing time due to tiny deviations at starting. The problem was overcome by installing hydraulic cylinders at the feet of pedestals and usage wooden scaffolding. All the floors were assembled in the same way as the first floor. Only height was in addition. To mount the rooms on the first floor, the hoist was used. The second-floor construction used a different method because the railway lifts stopped there. Those were two hanging lifts that used to mount the visitors to the top. It required an additional support frame on the pillar to take external load by the crane. The construction of stairs and elevators was made by a wooden staircase established along the beams of elevators. From the first-floor, spiral staircases were installed.
